Abstract: Closure (1) for receiving a section of a conductor assembly (71), comprising a housing (25) closable around the conductor assembly (71), and an electrode assembly (200), which comprises a movable portion comprising a contact surface (150) for mechanically contacting the conductor assembly (71), and a sensing electrode (140), operable as a first capacitor electrode of a sensing capacitor for sensing a voltage of the conductor (80). The closure further comprises urging means (160) for urging the movable portion of the electrode assembly (200) towards the conductor assembly (71) for establishing a mechanical surface contact between the contact surface (150) and the conductor assembly (71), when the housing (25) is closed around the conductor assembly (71).
